About Invert Image Colors

Every colour is replaced by its opposite: white turns black, blue turns orange, and so on. It recreates a film negative and can turn a white-background diagram into a dark-mode version.

Transparency is left unchanged, so a logo on a transparent background stays transparent.

Common uses

  • Making a dark version of a black-on-white diagram or scan.
  • Recreating a film negative effect.
  • Checking the balance of a design by looking at it inverted.

Questions

Can I turn a scanned negative into a photo?

Inverting gives a rough positive. Colour film negatives also have an orange tint, so colours may look off.

Is transparency kept?

Yes. Only the colours are inverted.

Can I undo it?

Yes. Inverting the result again gives back the original colours.
